using KTM outbound Port Klang route,
stop at Seri Jaya Station( behind leisure square, 1-2 km by walking), not take the route before, but not too far either
(if you able to waik)
or stop at Seri Setia  Station( in-front of Guinne Stout  company) , and catch a rapid bus to Sunway Pyramid.

ktm to subang jaya. rapid kl/ bas mini to sunway pyramid

The easiest is take lrt to kelana jaya station

Then take u623 bus which can be found below the kelana jaya lrt

When u wanna head back just reverse the procedure (ride the bus from the same location)

P/s You can take lrt from sentral....

i recommend this too...

alternative is to take rapid BET 3 from sentral to pyramid
